On Thursday a cold front will move in, dropping temps into the single digits. Conditions will remain well below freezing on Friday, before warming ever so on Saturday back into the high 30s.

What does all this mean?

Snow on surfaces will melt a bit today. Tomorrow, all that melt will turn back into a bitter, spiteful layer of ice. So if there’s snow anywhere that needs to be removed—CARS, SIDEWALKS, ROADWAYS, perhaps—DO IT NOW.

City of Hoboken snow removal efforts are continuing as street cleaning resumes today, but there’s only so much that can be done. Cars left unmoved create tremendous obstacles for the heavy machinery attempting to clear the streets.

“If two people in the middle of the block don’t move their car,” said Mayor Zimmer, “depending on how they are parked, there is potentially not that much we can do to clean that block,” according to the Hudson Reporter.
